Theres 2 types of tunerlock. There are just changing the security key - you can brute force this and then read with most tools (including mine). Then there is HPT proprietary tunerlock which applies to HPT COS, and that is an additional thing over the top of regular security lock. You can still read this my tool once you know the security key but you will have trouble with the HPT tunerlock.

For the record my tool will get there one day. Im playing around with different hardware at the moment as the AVT is prohibitively expensive in this part of the world. Once thats sorted I'll get back to it. Theres only so many hours in the week outside of work, and so many projects. Pretty cool that this uses bins.
